Answer:
The area of the window is of 840 square inches.
Step-by-step explanation:
To find the area of an trapezoid, we need to add the sum of the bases, multiply by the height, and then divide by 2.
Matematically:
In which 
and 
are the bases and h is the height.
In this question:
All the measures in inches, so the area is in square inches.
The area of the window is of 840 square inches.
Answer: The artist used 8.6 inches more of silver wire
Step-by-step explanation:
Perimeter of the square
P = 4*a
P = 4*a = 40 in
a = 10 in
Each side of the square has a length of 10 in
The diameter of the circle is equal to the length of the side of the square
Diameter = 10 in
Perimeter of the circle
P_c = 2*π*radius = π*diameter
P_c = (3.14)*10 in = 31.4 in
Inches of silver wire (square) = 40 in
Inches of copper wire (circle) = 31.4 in
40- 31.4 in = 8.6 in

Step-by-step explanation:
Answer:
mark=$2400 &Saul=$4800
Step-by-step explanation:
For mark:
p=$12000
r=4%
t=5 years
I=prt/100
12000*4*5/100= 2400
For Saul:
p=$10000
r=6%
t=8 years
SI=prt/100
10000*6*8/100= 4800
